摘要

背景：基底窦性室性心动过速（VT）传统上被认为是一种特发性心律失常。然而，它在结构性心脏病，特别是缺血性心脏病（IHD）患者中的发生往往未得到充分认识。病例总结：我们报告了两例有心肌梗死史的患者，他们表现为基底窦性室速。在这两例中，室速都是不可诱导的，两例患者的左心室射血分数（LVEF）都恢复了，这表明心律失常引起的心肌病有很大的负担。讨论：目前尚不清楚IHD是纯粹巧合还是促进心律失常发生的潜在底物。结论：基底结节性室性心动过速可发生于IHD患者，与特发性心外膜室性心动过速相似，近端心中静脉（MCV）消融可能有潜在的治疗效果。

Basal Crux Ventricular Tachycardia in Ischemic Heart Disease.

Background: Basal crux ventricular tachycardia (VT) is traditionally considered an idiopathic arrhythmia. However, its occurrence in patients with structural heart disease, especially ischemic heart disease (IHD), is often under recognised.

Case summary: We report two patients with a history of myocardial infarction who presented with basal crux VT. In both cases, VT was rendered non-inducible, and both patients experienced recovery of their left ventricular ejection fraction (LVEF), indicating a significant burden of arrhythmia-induced cardiomyopathy.

Discussion: It is unclear whether IHD is purely coincidental or contributes to the underlying substrate promoting arrhythmogenesis.

Conclusion: Basal crux VT can occur in patients with IHD and may resemble idiopathic epicardial VT. Ablation in the proximal middle cardiac vein (MCV) may be potentially curative.
